Congratulations on your high GPA and great scores, of course with the exception of the low reading, by any chance is English a 2nd language? If so schools do take that into consideration. I have worked with students who have gotten at 16 in reading and been accepted into dental school. I would make sure to have a good response if you are asked on an interview why you reading score was a 16.
If you have a certain school in mind I would definitely check out their stats for acceptance.
I don't think it should affect your chances. some schools put emphasis on the reading score because theres a lot of material to read in dental school but it shouldn't make or break you with a 16.
